Abstract

We demonstrate a new development environment "Information State Update" dialogue systems which allows non-expert developers to produce complete spoken dialogue systems based only on a Business Process Model (BPM) describing their application (e.g. banking, cinema booking, shopping, restaurant information). The environment includes automatic generation of Grammatical Framework (GF) grammars for robust interpretation of spontaneous speech, and uses application databases to generate lexical entries and grammar rules. The GF grammar is compiled to an ATK or Nuance language model for speech recognition. The demonstration system allows users to create and modify spoken dialogue systems, starting with a definition of a Business Process Model and ending with a working system. This paper describes the environment, its main components, and some of the research issues involved in its development.
